For example, it is possible to download part or all of these lists from this asset management platform 10.

[0035] In addition, a user terminal 60, a maintenance company terminal 62, and a parts company terminal 64 are communicably connected to the asset management platform 10. These terminals 60, 62, and 64 are each composed of a portable smartphone, a PC tablet, a personal computer installed in a maintenance company or a parts company, etc. In this embodiment, various information is transmitted and received between the asset management platform 10 and the user terminal 60, the maintenance company terminal 62, and the parts company terminal 64.

[0036] Next, an operation performed when the asset management platform 10 is registered in the center platform 40 in the photovoltaic power plant management system 1 of this embodiment will be described.

[0037] The owner of the asset management platform 10 sends a command to the control unit 12 of the asset management platform 10 to cooperate with the center platform 40. Such a command is issued, for example, by transmitting a command from a terminal (not shown) of the owner of the asset management platform 10 to the center platform 40, or by inputting a command to cooperate with the center platform 40 on the website of the asset management platform 10. When the reception means 14 of the asset management platform 10 receives a command to cooperate with the center platform 40, it transmits information related to the cooperation request to the center platform 40. After receiving the cooperation request from the asset management platform 10, the control unit 42 of the center platform 40 cooperates with the asset management platform 10 when it receives a command from the administrator of the center platform 40 to approve the cooperation. Specifically, the center platform 40 issues an account for the asset management platform 10 and transmits the account to the asset management platform 10. In this way, the asset management platform 10 and the center platform 40 are cooperated with each other. When cooperation is established between the asset management platform 10 and the center platform 40, various pieces of information stored in the storage unit 30 of the asset management platform 10 are transmitted to the center platform 40, and backup information of the asset management platform 10 is stored in the storage unit 43 of the center platform 40. As a result, even if the system of the asset management platform 10 goes down, it is possible to perform a recovery operation of the data stored in the storage unit 30 of the asset management platform 10 using the data transmitted from the center platform 40. In addition, information on maintenance companies, parts companies, and parts registered in the storage unit 30 of the asset management platform 10 is transmitted from the asset management platform 10 to the center platform 40, and is stored in a maintenance company database 44 and a parts database 46 of the center platform 40.As a result, by managing information on maintenance companies, parts companies, and parts registered in the memory units 30 of various asset management platforms 10 located throughout the country at the center platform 40, this information can be shared among multiple asset management platforms 10, as will be described later.

[0038] Next, the operation when the photovoltaic power plant management system 1 of this embodiment performs a status investigation operation and a repair operation of the photovoltaic equipment 52 of the photovoltaic power plant 50 will be described with reference to the flowcharts shown in Fig. 2 to Fig. 5.

[0039] First, the operation when the photovoltaic power plant management system 1 of the present embodiment performs a status survey task for the photovoltaic equipment 52 of the photovoltaic power plant 50 will be described with reference to the on-site status survey task flow shown in FIG.

[0040] In the asset management platform 10, when the data processing platform 70 receives the abnormality information of the solar power equipment 52 transmitted from the data processing platform 70 ("YES" in step St1), the data processing platform 70 transmits the abnormality information of the solar power equipment 52 to the asset management platform 10 of the user (step St2). In the data processing platform 70, when the reception means 14 receives the abnormality information and the abnormality detection means 16 detects an abnormality in the solar power equipment 52, the abnormality information of the solar power equipment 52 is transmitted to the user terminal 60. This allows the owner of the solar power equipment 52 to know that some abnormality has occurred in the solar power equipment 52 through the user terminal 60. In addition, when the abnormality detection means 16 detects an abnormality in the solar power equipment 52, it is determined whether or not the abnormality can be handled within the internal system of the company that owns the data processing platform 70 (step St3). Specifically, the storage unit 30 of the asset management platform 10 stores information on whether the internal system of the company that owns the data processing platform 70 can handle the situation investigation work, and whether the internal system of the company that owns the data processing platform 70 can handle it is determined based on the information stored in the storage unit 30. At this time, the storage unit 30 stores the type of situation investigation work that can be handled by the internal system of the company that owns the data processing platform 70, and when the abnormality detection means 16 detects an abnormality in the solar power facility 52, the type of situation investigation work that can be handled is notified to, for example, the user terminal 60 based on the information stored in the storage unit 30, and a command on whether to perform the situation investigation work by the internal system of the company is sent from the user terminal 60 to the asset management platform 10, thereby determining whether to handle it by the internal system of the company that owns the data processing platform 70. If the internal system of the company that owns the data processing platform 70 cannot handle it ("NO" in step St3), the first authority is granted and information is disclosed to the external contractor registered in advance in the asset management platform 10 of the user (step St4). The information to be made public is determined based on the authority given to the outsourcee.For example, until the outsourcing contractor is finalized, only a part of the information on the solar power plant 50 and the solar facility 52 is disclosed to the outsourcing contractor due to the first authority granted to the outsourcing contractor.

[0041] Specifically, the control unit 12 displays information on the solicitation of the status investigation service of the solar facility 52 on the website of the asset management platform 10. Here, the information on the solicitation of the status investigation service of the solar facility 52 includes the installation location of the solar power plant 50, the specific specifications of the solar facility 52, the date and time when the abnormality of the solar facility 52 was detected by the abnormality detection means 16, the history of the past status investigation service and repair service of the solar facility 52, and the like. As described above, only a part of the information on the solar power plant 50 and the solar facility 52 is displayed on the website of the asset management platform 10. In addition, the information on the solicitation of the status investigation service of the solar facility 52 is transmitted to the terminal 62 of the maintenance company stored in the storage unit 30. As a result, each maintenance company that has received the information on the solicitation of the status investigation service can apply for the status investigation service of the solar facility 52 through the website of the asset management platform 10. The application information includes schedule information regarding when the solar power equipment 52 status inspection work will be carried out, the cost required for the status inspection work, the number of workers who will carry out the solar power equipment 52 status inspection work, the qualifications of the workers, and company information of the maintenance company (step St5).

[0042] Furthermore, in this embodiment, maintenance companies to be recruited are determined based on the location information of the solar power plant 50 having the solar facility 52 and the location information of each maintenance company, and information regarding the recruitment for status investigation work is transmitted to this determined maintenance company by the transmission means 18. Specifically, for example, maintenance companies located within a predetermined distance from the solar power plant 50 having the solar facility 52 that requires status investigation work, or maintenance companies within a predetermined travel time from the solar power plant 50 having the solar facility 52 that requires status investigation work, are determined as maintenance companies to be recruited, and information regarding the recruitment for status investigation work is transmitted to this determined maintenance company by the transmission means 18.

[0043] When the reception means 14 receives information on the status investigation work from each maintenance company (specifically, an application for the status investigation work), the calculation means 20 calculates the total loss amount for each maintenance company based on the cost required for inspection of the solar power plant 50's solar facility 52 and the loss amount due to the inability to generate power during the inspection of the solar power plant 50's solar facility 52. ​​For example, when the number of days from when an abnormality in the solar facility 52 is detected by the abnormality detection means 16 to the day when the status investigation work of the solar facility 52 is scheduled to be performed by a certain maintenance company in the application information of the maintenance company is three days, the calculation means 20 calculates the total loss amount when the maintenance company is requested to perform the work based on the cost required for the status investigation work by the maintenance company and the loss amount due to the inability to generate power by the solar facility 52 for three days. Note that when the total loss amount is calculated, if the amount of power generation is reduced due to an abnormality in the solar facility 52, the loss amount due to the reduction in the amount of power generation may also be taken into consideration. The control unit 12 displays information on the application for the status investigation work of the solar facility 52 from each maintenance company on the website of the asset management platform 10. At this time, the sorting means 22 sorts the maintenance companies based on the total loss amount calculated by the calculation means 20, and the maintenance companies sorted by the sorting means 22 are displayed on the website of the asset management platform 10 in the order of the maintenance companies sorted by the sorting means 22. The owner of the solar power plant 50 then selects, for example, one maintenance company on the website from among the multiple maintenance companies (specifically, the maintenance companies that have applied for the status investigation work) displayed on the website of the asset management platform 10 by the selection means 24 (step St6). This determines the contractor for the status investigation work. In addition, the maintenance company selected by the owner of the solar power plant 50 by the selection means 24 is further granted a second authority as necessary (step St7). Here, according to the second authority granted to the outsourcee after the contractor is determined, more information on the solar power plant 50 and the solar facility 52 is made available to the outsourcee than when the first authority is granted.For example, when the first authority is granted, only general information about the specific specifications of the solar facility 52 and the history of past status investigation work and repair work of the solar facility 52 is made public, but when the second authority is granted, detailed information about the specific specifications of the solar facility 52 and the history of past status investigation work and repair work of the solar facility 52 is made public. In more detail, for example, when the first authority is granted, the design drawings of the solar power plant 50 and the solar facility 52 are not made public to the outsourcee, but information about the design drawings of the solar power plant 50 and the solar facility 52 is given to the outsourcee to whom the second authority is granted. As a result, more information than the information made public when applying is communicated to the outside business operator performing the status investigation work, so that the outside business operator can perform the status investigation work more appropriately.

[0044] Then, the control unit 12 requests the maintenance company selected by the owner of the solar power plant 50 using the selection means 24 to carry out a status investigation work, and concludes a contract (step St8). Specifically, the transmission means 18 transmits the request information for the status investigation work of the solar equipment 52 of the solar power plant 50 to the terminal 62 of the selected maintenance company. At this time, the sorting means 22 rearranges the maintenance companies based on the total loss amount calculated by the calculation means 20, and the maintenance companies with smaller total loss amounts are displayed at the top of the website, so that the owner of the solar power plant 50 can select a maintenance company with a smaller total loss amount.

[0045] Thereafter, the company that owns the asset management platform 10 ("YES" in step St3) or the entrusted external company (step St8) starts the on-site situation investigation work (step St9). When the situation investigation work of the solar power facility 52 is performed in this manner, the worker of the company that owns the asset management platform 10 or the entrusted external company reports the completion of the situation investigation work to the asset management platform 10 by updating the report on the website of the asset management platform 10 or sending an email with the report attached to the asset management platform 10. When the reception means 14 of the asset management platform 10 receives the report on the completion of the situation investigation work from the maintenance company, the report content is displayed on the website of the asset management platform 10. This allows the owner of the solar power plant 50 to check the report content of the situation investigation work displayed on the website of the asset management platform 10 (step St10). In addition, the report content is stored in the memory unit 30 of the asset management platform 10 (step St11). The report of the status investigation work includes whether or not parts need to be replaced, and if so, information on the parts that need to be replaced. If repair work for the solar power plant 52 is not required based on the report made by the maintenance company, a series of operations in the solar power plant management system 1 is completed (step St12). On the other hand, if repair work for the solar power plant 52 is required based on the report made by the maintenance company, repair work for the solar power plant 52 as described below is performed. If the repair work required at the time of inspection is simple, the maintenance company performing the status investigation work may also perform the repair work at the same time as the inspection.

[0046] Furthermore, if the above-mentioned status investigation work cannot be handled by the company's internal system, or cannot be handled by an external contractor registered with the asset management platform 10, an inquiry is made to the center platform. Such inquiries to the center platform will be described later.

[0047] The operation when repair work for the photovoltaic equipment 52 of the photovoltaic power plant 50 is performed by the photovoltaic power plant management system 1 of this embodiment will be described with reference to the on-site repair work flow shown in FIG.

[0048] When it is determined that on-site repair work is necessary based on the report contents of the status investigation work ("YES" in step St101), it is determined whether or not the repair work can be handled by the internal system of the company that owns the data processing platform 70 (step St102). Specifically, the storage unit 30 of the asset management platform 10 stores whether or not the repair work can be handled by the internal system of the company that owns the data processing platform 70, and it is determined whether or not the repair work can be handled by the internal system of the company that owns the data processing platform 70 based on the information stored in the storage unit 30. At this time, the storage unit 30 stores the type of repair work that can be handled by the internal system of the company that owns the data processing platform 70, and when the abnormality detection means 16 detects an abnormality in the solar power facility 52, the type of repair work that can be handled is notified to, for example, the user terminal 60 based on the information stored in the storage unit 30, and a command as to whether or not to perform the repair work by the internal system of the company is sent from the user terminal 60 to the asset management platform 10, so that it may be determined whether or not the repair work can be handled by the internal system of the company that owns the data processing platform 70. If the internal system of the company that owns the data processing platform 70 is not capable of handling the request ("NO" in step St102), the first authority is granted to the outsourcing company that is registered in advance in the user's asset management platform 10, and information is disclosed (step St103). Here, the information to be disclosed is determined based on the authority granted to the outsourcing company. For example, until the outsourcing company is determined, only a portion of the information related to the solar power plant 50 and the solar facility 52 is disclosed to the outsourcing company due to the first authority granted to the outsourcing company.

[0049] Specifically, the control unit 12 displays information regarding the recruitment of repair work for the solar power facility 52 on the website of the asset management platform 10. Here, the information regarding the recruitment of repair work for the solar power facility 52 includes the installation location of the solar power plant 50, the specific specifications of the solar power facility 52, the date and time when an abnormality in the solar power facility 52 was detected by the abnormality detection means 16, the history of past status investigation work and repair work for the solar power facility 52, and the like. As described above, only a part of the information regarding the solar power plant 50 and the solar power facility 52 is displayed on the website of the asset management platform 10. In addition, the information regarding the recruitment of repair work for the solar power facility 52 is transmitted to the terminal 62 of the maintenance company stored in the storage unit 30. As a result, each maintenance company that receives the information regarding the recruitment of repair work can apply for the repair work for the solar power facility 52 through the website of the asset management platform 10. The repair information includes schedule information on when the repair work of the solar power facility 52 will be performed, the cost required for the repair work, the number of workers who will perform the repair work of the solar power facility 52, the qualifications of the workers, and company information of the maintenance company (step St104). In this embodiment, a maintenance company to be recruited is determined based on the location information of the solar power plant 50 having the solar power facility 52 and the location information of each maintenance company, and information regarding the recruitment of repair work is transmitted to this determined maintenance company by the transmission means 18. Specifically, for example, a maintenance company within a predetermined distance from the solar power plant 50 having the solar power facility 52 that needs repair work, or a maintenance company within a predetermined travel time from the solar power plant 50 having the solar power facility 52 that needs repair work, is determined as a maintenance company to be recruited, and information regarding the recruitment of repair work is transmitted to this determined maintenance company by the transmission means 18.

[0050] When the reception means 14 receives information on the repair work from each maintenance company (specifically, an application for the repair work), the calculation means 20 calculates the total loss amount for each maintenance company based on the cost required for repairing the solar power plant 50's solar facility 52 and the loss amount due to the inability to generate power while the solar power plant 50's solar facility 52 is being repaired. For example, when the number of days from when an abnormality in the solar facility 52 is detected by the abnormality detection means 16 to the day when the maintenance company is scheduled to perform the repair work on the solar facility 52 in the application information of the maintenance company is 10 days, the calculation means 20 calculates the total loss amount when the maintenance company is requested to perform the repair work based on the cost required for the repair work by the maintenance company and the loss amount due to the inability to generate power by the solar facility 52 for 10 days. Note that when the total loss amount is calculated, if the amount of power generation is reduced due to an abnormality in the solar facility 52, the loss amount due to the reduction in the amount of power generation may also be taken into consideration. The control unit 12 displays the information on the application for the repair work of the solar facility 52 from each maintenance company on the website of the asset management platform 10. At this time, the sorting means 22 sorts the maintenance companies based on the total loss amount calculated by the calculation means 20, and the maintenance companies sorted by the sorting means 22 are displayed on the website of the asset management platform 10 in the order of the maintenance companies sorted by the sorting means 22. Then, the owner of the solar power plant 50 selects one maintenance company from among the maintenance companies (specifically, the maintenance companies that have applied for the repair work) displayed on the website of the asset management platform 10 by the selection means 24, for example, on the website (step St105). This determines the contractor for the repair work. The maintenance company selected by the owner of the solar power plant 50 by the selection means 24 is granted a second authority, which is a further authority (step St106). Here, according to the second authority granted to the outsourcee after the contractor is determined, more information on the solar power plant 50 and the solar facility 52 is made available to the outsourcee than when the first authority is granted.For example, when the first authority is granted, only general information is made public about the specific specifications of the solar facility 52 and the history of past status investigations and repair work on the solar facility 52, but when the second authority is granted, detailed information is made public about the specific specifications of the solar facility 52 and the history of past status investigations and repair work on the solar facility 52. ​​This allows the external business operator performing the repair work to perform the repair work more appropriately, since more information is communicated to the external business operator performing the repair work than is made public when applying.

[0051] Then, the control unit 12 requests the maintenance company selected by the owner of the solar power plant 50 using the selection means 24 to carry out repair work, and concludes a contract (step St107). Specifically, the transmission means 18 transmits request information for repair work of the solar equipment 52 of the solar power plant 50 to the terminal 62 of the selected maintenance company. At this time, the sorting means 22 rearranges the maintenance companies based on the total loss amount calculated by the calculation means 20, and the maintenance companies with smaller total loss amounts are displayed at the top of the website, so that the owner of the solar power plant 50 can select a maintenance company with a smaller total loss amount.

[0052] Thereafter, the company that owns the asset management platform 10 ("YES" in step St102) or the entrusted external company (step St107) starts the repair work on site (step St108). When the repair work of the solar power plant 52 is performed in this manner, the worker of the company that owns the asset management platform 10 or the entrusted external company reports the completion of the repair work to the asset management platform 10 by updating the repair work report on the website of the asset management platform 10 or sending an email with the report attached to the asset management platform 10. When the reception means 14 of the asset management platform 10 receives the report on the completion of the repair work from the maintenance company, the report content is displayed on the website of the asset management platform 10. This allows the owner of the solar power plant 50 to check the report content of the repair work displayed on the website of the asset management platform 10 (step St109). Also, when the repair work is completed (step St110), the report content is stored in the memory unit 30 of the asset management platform 10 (step St111). In this manner, the repair work is completed (step St112).

[0053] Furthermore, if the repair work cannot be handled by the company's internal system or by an external contractor registered with the asset management platform 10, an inquiry is made to the center platform. Such inquiries to the center platform will be described later.

[0054] Next, the flow of parts purchasing required for the above repair work will be explained with reference to FIG.

[0055] When it is determined that a part needs to be replaced based on the results of the on-site investigation as shown in the flow chart of FIG. 2 ("YES" in step St201), it is determined whether the company that owns the asset management platform 10 has stock of related parts (step St202). When the company that owns the asset management platform 10 has stock of related parts ("YES" in step St202), the repair contractor and the logistics contractor decide which parts to use (step St209). On the other hand, when the company that owns the asset management platform 10 does not have stock of related parts ("NO" in step St202), it is determined whether the parts can be purchased within the company (step St203). When the parts cannot be purchased within the company ("NO" in step St203), information on the purchase of parts is disclosed to an external contractor that is registered in advance in the asset management platform 10 of the user (step St204). Specifically, information on the purchase of parts is transmitted to the terminal 64 of the parts company stored in the storage unit 30. As a result, each parts company that has received the information regarding the purchase of parts presents an estimate and delivery date for the parts on the website of the asset management platform 10 (step St205).

[0056] Then, the asset management platform 10 determines the outsourcing company from which the parts are purchased (step St206). Such a determination may be made by the user through the user terminal 60. Once the outsourcing company from which the parts are purchased is determined, the outsourcing company is screened (step St207). Here, the outsourcing company's screening includes either or both of an external screening by an insurance company and an internal screening to determine whether the cost of the parts is reasonable. Then, if there is no problem with the screening ("YES" in step St207), the parts are purchased (step St208). After that, the repair work outsourcing company and the logistics work are consulted to determine which parts to use (step St209). In this way, the parts purchasing work is completed (step St210).

[0057] If the part required for replacement cannot be obtained from a parts company registered in the storage unit 30 of the asset management platform 10, the user performs a procedure for purchasing the part from a parts EC site provided by the center platform 40 and specifies the delivery location of the part. A list of parts available for purchase on the parts EC site provided by the center platform 40 is stored in the parts database 46.

[0058] In addition, a case where the above-mentioned status investigation work and repair work cannot be handled by the company's internal system, and cannot be handled by an external contractor registered in the asset management platform 10 will be described. When the user's asset management platform 10 does not have enough resources ("YES" in step St301), the transmission means 18 of the asset management platform 10 transmits information regarding a request for information provision to the center platform 40. Here, when the asset management platform 10 is registered in the center platform 40 ("YES" in step St302), the center platform 40 searches for a contractor according to the work content (step St304). On the other hand, when the asset management platform 10 is registered in the center platform 40 ("NO" in step St302), it is necessary for the asset management platform 10 to apply for registration to the center platform 40 (step St303). When the asset management platform 10 is registered in the center platform 40 in this way, the center platform 40 searches for a contractor according to the work content, and the search result is transmitted from the center platform 40 to the asset management platform 10. Then, when the search results are displayed on the website of the asset management platform 10 (step St305), the asset management platform 10 becomes able to contact the outsourcee displayed on this website (step St306). In this way, the outsourcee companies registered in the asset management platform 10 are stored in the storage unit 30 of the user's asset management platform 10 and registered in the asset management platform 10 (step St307). In this way, the user becomes able to outsource work to the newly registered outsourcee.

[0059] More specifically, the asset management platform 10 is able to confirm from the center platform 40 a part or all of the list of maintenance companies stored in the maintenance company database 44. Here, when the asset management platform 10 is able to confirm from the center platform 40 a part, but not all, of the list of maintenance companies stored in the maintenance company database 44, the asset management platform 10 is able to confirm from the center platform 40 information on a predetermined number of maintenance companies in order of proximity to the location where the solar power plant 50 is installed or in order of shortest travel time. As a result, even if the storage unit 30 of the asset management platform 10 does not store information on maintenance companies that can carry out status investigation work and repair work on the solar power facility 52 of the solar power plant 50 corresponding to this asset management platform 10, by transmitting information regarding a request for information provision to the center platform 40 and making it possible to confirm from the center platform 40 a part or all of the list of maintenance companies stored in the maintenance company database 44 of this center platform 40, the control unit 12 can reliably carry out status investigation work and repair work on the solar power facility 52.

[0060] The photovoltaic power plant management system 1 of the present embodiment configured as described above includes a photovoltaic power plant 50 having a photovoltaic facility 52, an asset management platform 10 provided in correspondence with the photovoltaic power plant 50 and having a reception means 14, an abnormality detection means 16, a control unit 12 functioning as a transmission means 18 by executing a program, and a storage unit 30 for storing information about maintenance companies, and a center platform 40 communicably connected to the asset management platform 10 and having a database 44 of maintenance companies. In addition, in the asset management platform 10, when the reception means 14 receives abnormality information about the photovoltaic facility 52 and the abnormality detection means 16 detects an abnormality in the photovoltaic facility 52, it is determined whether the asset management platform 10 can handle the status investigation work of the photovoltaic facility 52, and if the asset management platform 10 cannot handle the status investigation work of the photovoltaic facility 52, a request for information provision is transmitted from the asset management platform 10 to the center platform 40 by the transmission means 18, and the information of the maintenance companies that can perform the work stored in the database 44 of the center platform 40 can be confirmed from the asset management platform 10. According to such a solar power plant management system 1, if the asset management platform 10 is unable to handle the task of investigating the status of the solar power equipment 52, a request for information is sent from the asset management platform 10 to the center platform 40 by the transmission means 18, and information on maintenance companies that are able to perform the work and stored in the database 44 of the center platform 40 can be confirmed from the asset management platform 10, thereby eliminating the need to contact maintenance companies other than those stored in the memory unit 30 of the asset management platform 10, thereby improving convenience.

[0061] Here, the determination of whether the asset management platform 10 can handle the status investigation work of the solar power facility 52 means that it is determined whether it can be handled by the internal system of the company that owns the data processing platform 70, and if it is not possible to handle it by the internal system of the company that owns the data processing platform 70, it is determined whether it can be handled by an external contractor registered in the storage unit 30 of the asset management platform 10. In addition, a case where the asset management platform 10 cannot handle the status investigation work of the solar power facility 52 means a case where it is not possible to handle it by the internal system of the company that owns the data processing platform 70 and also not possible to handle it by an external contractor registered in the storage unit 30 of the asset management platform 10. Note that this embodiment is not limited to such an embodiment. In another embodiment, the determination of whether the asset management platform 10 can handle the status investigation work of the solar power facility 52 may be only one of the following: it is determined whether it can be handled by the internal system of the company that owns the data processing platform 70, and it is determined whether it can be handled by an external contractor registered in the storage unit 30 of the asset management platform 10. In addition, a case in which the asset management platform 10 is unable to handle the status investigation work of the solar power equipment 52 may be either that it is not possible to handle it within the internal structure of the company that owns the data processing platform 70, or that it is not possible to handle it by an external contractor registered in the memory unit 30 of the asset management platform 10.

[0062] Moreover, in the photovoltaic power plant management system 1 of the present embodiment, information regarding the solicitation of a status investigation service for the photovoltaic facility 52 is displayed on the website of the asset management platform 10, and at this time, a maintenance company to be recruited is determined based on the location information of the photovoltaic power plant 50 having the photovoltaic facility 52 and the location information of each maintenance company. Moreover, when a maintenance company to perform the status investigation service is selected from a plurality of maintenance companies by the selection means 24 on the website of the asset management platform 10, a request to request the selected maintenance company to perform the status investigation service is transmitted to the terminal 62 of the selected maintenance company by the transmission means 18. According to such a photovoltaic power plant management system 1, a maintenance company located, for example, close to the location of the photovoltaic power plant 50 among various maintenance companies is recruited, so that a more appropriate maintenance company can be selected to perform the status investigation service.

[0063] In the photovoltaic power plant management system 1 of the present embodiment, information on the solicitation of the status investigation service of the photovoltaic facility 52 is displayed on the website of the asset management platform 10, and at this time, the calculation means 20 calculates a total loss amount for each maintenance company based on the cost required for the inspection of the photovoltaic facility 52 and the loss amount due to the inability to generate power while the photovoltaic facility 52 is being inspected, and the sorting means 22 sorts the maintenance companies based on the total loss amount calculated by the calculation means 20, and the maintenance companies sorted by the sorting means 22 are displayed on the website of the asset management platform 10 in the order of the maintenance companies sorted by the sorting means 22. In addition, when a maintenance company that will perform the status investigation service is selected from a plurality of maintenance companies by the selection means 24 on the website of the asset management platform 10, a request to request the selected maintenance company to perform the status investigation service is transmitted to the terminal 62 of the selected maintenance company by the transmission means 18. According to such a photovoltaic power plant management system 1, it is possible to select a maintenance company that will have a smaller total loss amount from various maintenance companies by the selection means 24 and have the maintenance company perform the status investigation service.

[0064] In the photovoltaic power plant management system 1 of the present embodiment, when the receiving means 14 receives abnormality information of the photovoltaic facility 52 in the asset management platform 10 and detects an abnormality in the photovoltaic facility 52 by the abnormality detection means 16, information on the recruitment of the status investigation work of the photovoltaic facility 52 is displayed on the website of the asset management platform 10, and at this time, the maintenance company that applies is granted a first authority, so that some of the information on the photovoltaic facility 52 or the photovoltaic power plant 50 is made public, and when a maintenance company that performs the status investigation work is selected from a plurality of maintenance companies by the selection means 24 on the website, a request to request the selected maintenance company to perform the status investigation work is transmitted to the terminal 62 of the selected maintenance company by the transmission means 18, and at this time, the selected maintenance company is granted a second authority, so that more information on the photovoltaic facility 52 or the photovoltaic power plant 50 is given to the selected maintenance company than the information that is made public by the first authority. As a result, more information than the information made public when applying is communicated to the external business operator that performs the status investigation work, and these works can be performed more appropriately.

[0065] Furthermore, in the solar power plant management system 1 of this embodiment, when the asset management platform 10 determines whether or not the asset management platform 10 can handle the status investigation work of the solar equipment 52, if the owner of the asset management platform 10 or the maintenance company stored in the memory unit 30 is unable to perform the status investigation work of the solar equipment 52, it is determined that the asset management platform 10 cannot handle the status investigation work of the solar equipment 52.

[0066] Furthermore, in the solar power plant management system 1 of this embodiment, information regarding the solicitation of applications for status investigation services for the solar power plant 52 is displayed on the website of the asset management platform 10, and on the website, a selection means 24 is used to select a maintenance company to carry out the status investigation services from among a plurality of maintenance companies.

[0067] Furthermore, in the photovoltaic power plant management system 1 of this embodiment, when the receiving means 14 receives a report on the status investigation work from the maintenance company that performed the status investigation work, the report contents are displayed on the website of the asset management platform 10.

[0068] In the solar power plant management system 1 of the present embodiment, when the asset management platform 10 determines that the solar facility 52 needs to be repaired, it is determined whether the asset management platform 10 can handle the repair work of the solar facility 52. ​​If the asset management platform 10 cannot handle the repair work of the solar facility 52, the transmission means 18 transmits information regarding a request for information provision from the asset management platform 10 to the center platform 40, and the information of the maintenance company that can perform the work stored in the database 44 of the center platform 40 can be confirmed from the asset management platform 10. According to such a solar power plant management system 1, if the asset management platform 10 cannot handle the repair work of the solar facility 52, the transmission means 18 transmits information regarding a request for information provision from the asset management platform 10 to the center platform 40, and the information of the maintenance company that can perform the work stored in the database 44 of the center platform 40 can be confirmed from the asset management platform 10. This eliminates the need to consult with maintenance companies other than the maintenance companies stored in the storage unit 30 of the asset management platform 10, thereby improving convenience.

[0069] Here, the determination of whether the asset management platform 10 can handle the repair work of the solar power facility 52 means that it is determined whether the repair work can be handled by the internal system of the company that owns the data processing platform 70, and if the repair work cannot be handled by the internal system of the company that owns the data processing platform 70, it is determined whether the repair work can be handled by an external contractor registered in the storage unit 30 of the asset management platform 10. In addition, a case where the asset management platform 10 cannot handle the repair work of the solar power facility 52 means a case where the repair work cannot be handled by the internal system of the company that owns the data processing platform 70 and also cannot be handled by an external contractor registered in the storage unit 30 of the asset management platform 10. Note that this embodiment is not limited to such an embodiment. In another embodiment, the determination of whether the asset management platform 10 can handle the repair work of the solar power facility 52 may be only one of the following: it is determined whether the repair work can be handled by the internal system of the company that owns the data processing platform 70, and it is determined whether the repair work can be handled by an external contractor registered in the storage unit 30 of the asset management platform 10. In addition, a case in which the asset management platform 10 is unable to handle repair work for the solar power equipment 52 may be either that the internal system of the company that owns the data processing platform 70 is unable to handle it, or that an external contractor registered in the memory unit 30 of the asset management platform 10 is unable to handle it.

[0070] Moreover, in the photovoltaic power plant management system 1 of the present embodiment, information regarding the recruitment of repair work for the photovoltaic facility 52 is displayed on the website of the asset management platform 10, and at this time, a maintenance company to be recruited is determined based on the location information of the photovoltaic power plant 50 having the photovoltaic facility 52 and the location information of each maintenance company.
